The Warmer Homes Scheme does not require every applicant to install a particular heating system. Eligibility normally depends on factors such as owning and living in the property, receiving a qualifying social welfare payment, and the home’s age and energy performance. An SEAI assessment will identify whether insulation, heating controls, a boiler or heating-system upgrade, or other works are suitable; the recommended measures depend on the property and existing system. Final approval and the works offered are decided by SEAI and its appointed contractors, so check the current requirements on the official SEAI website.
